Just to update you, an email was sent today by the company that we are subbing off totally denying any responsibility and offering to show our method of cleaning to prove that it was not us. The reply? there was none, and they did not invite us to attend a meeting. The company that we are subbing off feel that they are trying it on. well, we shall see. At least I will get a bit of sleep tonight. Will keep you informed. Mike

I think in fairness its a known fact that scraping glass with any type of metal blade and no matter which  direction it is used whether wet or dry has the potential to leave some scratch marks, its safer all round if you explain to your customer or to the contractor that scratches will be unavoidable if their windows will require the use of a metal scraper. Just come across genuine explain the potential outcome and have them to sign a waiver and you have all angles covered.

You must also take into consideration that glass manufacturers will always recommend that metal blade scrapers should never be used on any type of glass.

Let's just assume it went to court

It still doesn't explain why he would 'look an idiot' especially to a court where they hearing circumstantial statements. Maybe you meant 'look guilty' which wouldn't be the case either.
